20230037291 · 2023-02-09 ·

Preparing MAX phase structures includes forming a gel including a transition metal M, a Group 3A or Group 4A metal or semimetal A, and an acidic chelating agent or gelling agent X. X includes one or both of carbon and nitrogen. Preparing the MAX phase structures further includes shaping the gel to yield a shaped gel and heating the shaped gel to yield carbonaceous MAX phase structures with a composition represented by M.sub.n+1AX.sub.n, wherein n is 1, 2, 3, or 4. The MAX phase structures can be thick films, microspheres, or microwires.

Method for producing an object from a precursor, and use of a radically crosslinkable resin in an additive production method

A process for producing an object from a precursor comprises the steps of: I) depositing a free-radically crosslinked resin atop a carrier to obtain a ply of a construction material joined to the carrier which corresponds to a first selected cross section of the precursor; II) depositing a free-radically crosslinked resin atop a previously applied ply of the construction material to obtain a further ply of the construction material which corresponds to a further selected cross section of the precursor and which is joined to the previously applied ply; III) repeating step II) until the precursor is formed; IV) treating the precursor obtained after step III) under conditions sufficient to at least partially trimerize to isocyanurate groups NCO groups present in the free-radically crosslinked resin of the obtained precursor to obtain the object.

METHODS OF TRANSFERRING PILLARS FROM PILLAR DELIVERY FILMS

Pillar delivery films for vacuum insulated glass units are disclosed. The delivery films include a support film or pocket tape, a sacrificial material on the support film, and a plurality of pillars. The pillars are at least partially embedded in the sacrificial material or formed within sacrificial material molds, and the sacrificial material is capable of being removed while leaving the pillars substantially intact. Methods of transferring pillars to a substrate using the pillar delivery films are disclosed. In order to make an insulated glass unit, the delivery films are laminated to a receptor such as a glass pane, and the support film and sacrificial material are removed to leave the pillars remaining on the glass.

11707556 · 2023-07-25 · ·

A method of manufacturing a therapeutic material incorporating a soft thermoformable elastomer with a phase change material exhibiting high latent heat of fusion. The compound provides elasticity, softness, formability, and heat over an extended duration and to facilitate prolonged skin contact at elevated temperatures. Used in combination with active ingredients the increased temperature and formability provides enhanced transdermal delivery through the skin. Thermoplastic elastomers may be manufactured by mixing together plasticizing oil, a triblock copolymer, a paraffinic substance and one or more additives, e.g., an antioxidant, an antimicrobial agent, and/or other additives to form a mixture which melted then cooled into the thermoplastic elastomer. During cooling, the thermoplastic elastomer may be molded or otherwise formed into any number of articles including, but not limited to, prosthetic liners, prosthetic sleeves, external breast prostheses, breast enhancement bladders, masks, wound dressing sheets, wound dressing pads, socks, gloves, malleolus pads, metatarsal pads, shoe insoles, urinary catheters, vascular catheters, and balloons for medical catheters both vascular as well as urinary. Active ingredients are preferably added to the cooling thermoplastic elastomer when the temperature is below 100° F. to prevent heat degradation and/or breakdown of vital proteins.
